![]() I used Diptrace initially, but then switched over to EasyEDA since I plan to send it to JLCPCB for the best cost and all their components from LCSC have the included the PCB footprint. ![]() So, this is my first mostly SMD PCB with standalone ATMEGA328P-PU on a PCB at least. I wanted to do this one that way as well, but realized it would have been a bear to make DIY and mostly THT wasn't the direction to go. ![]() I make all my own components as some of the 'factory' designs are not suitable for what I want).Just designed my first "real" PCB that I plan to send out for manufacture in the next day or so. It could well be I am not using the software properly, but I've looked around and clicked on everything I can find in order to try and do these tasks and if I cannot do it, this would be a good feature request. ![]() If I could rotate freely the pads once I'd selected the rectangular hole this would be perfect as I could align the holes with the pins no problems If you refer to the attached image you can see how the socket's pins are aligned and there is no way I can find to align the pattern's pads to suit their position, meaning I am stuck with large holes and very little solder area. I can of course make the 'holes' rectangular using the pad properties dialogue, giving me much tighter and physically stronger fit and more solder area but no matter how much I mess around with it, the rectangle runs the wrong way to accept the pins on the socket, which are shaped in a circle to match the valve pins themselves. Either way it leaves very little pad left with which to solder onto. I can make the outside polygonal, or even oblong or rectangular but I can't make them any bigger without fouling each other. The only pads I can create that will accommodate these pins are through holes at 3mm diameter with 2.8mm holes. The pins coming out of the socket are gold rectangular pins 0.5mm thick, 2.75mm wide and 8mm long. It is one of the more complicated patterns to do with tricky angles and pad spacing to be worked out but a decent datasheet for the sockets made things a lot easier. I have made a 9-pin valve component (for 12A series valves) in the component designer and am wanting to make a corresponding footprint/pattern for the sockets I have purchased for the project. The pad options are already very well thought-out and comprehensive but I have a situation where I have found a limitation with them and thus cannot position pads exactly how I want them. For example, I've created an amplifier component with 5 pins but I cannot get the pin numbers to show in the right orientation - pins on the top and bottom always have the numbers at 90degrees to where I want them and though I can move them with F10 I cannot rotate them to view them the way I want to.Īnother related question (that I don't think warrants a new topic) is pad creation, placement and orientation in the footprint/pattern editor. I know some information can be moved around using F10 but this is not completely configurable either, meaning I often have to mess about with right-click properties, marking positions and other options in order to get the markings where I want them and even then I can't get everything sitting and orientated where I want it displayed. Regarding component creation what, other than defining origin, determines where and how RefDes and other markings appears next to a component when it is inserted into a schematic Some components I have made when applied to a schematic have the markings either in the wrong place, touching the component or not where I would have put it if I'd had the option. I'm not sure about all the right termsfor things but I'll try to get my question across so it can be understood.
